Italian outlets report that Google's AI Overview feature told searchers that Claudio Zorzi, head of orthopedics and traumatology at the IRCCS Sacro Cuore Don Calabria hospital in Negrar (Verona), had died. According to the hospital, the surgeon is alive and operating, and the error probably came from confusion with a general practitioner of the same name who died. The false news is reported to have circulated since April 2025 and to have recurred. Zorzi said he felt uncomfortable because people who think he is dead do not look for him, and he reported the notice to the postal police. On 15 October 2025 the hospital served Google, through its lawyers, with a formal cease-and-desist and default notice and reserved a damages claim. No Google response was found. The AI Overview output itself was not inspected.

24 Oct 2025United KingdomMicrosoft Copilot (reported)
On 24 October 2025 West Midlands Police gave Birmingham City Council's Safety Advisory Group a written report that cited a Maccabi Tel Aviv v West Ham match on 9 November 2023 that never took place. The group had advised on 16 October that Aston Villa give no tickets to Maccabi Tel Aviv supporters for the 6 November 2025 match. In January 2026 the Chief Constable said the error arose from use of Microsoft Copilot, after earlier telling MPs it came from a Google search. The inspectorate found the ban advice predated the report and said confirmation bias influenced the force's assessments to the group. The sources do not show the Copilot output caused the ban.

In December 2025 Cape Breton fiddler Ashley MacIsaac said a First Nation north of Halifax cancelled his concert planned for 19 December after reading a Google AI-generated search summary that said he had convictions for sexual offences. He says the statements were false and came from online articles about another man in Atlantic Canada with the same last name. The First Nation apologised in writing and Google amended the search results. MacIsaac says he feared for his safety and worries about other lost work. In a statement of claim filed in February 2026 in the Ontario Superior Court of Justice he seeks damages of 1.5 million from Google (US dollars in the Globe and Mail copy of the Canadian Press story, no currency stated in the CBC copy). None of its claims has been tested in court, and the claim says Google did not admit responsibility.

Apr 2025 to May 2025Event location unknownCoCounsel, Westlaw Precision and Gemini (reported)
In an order dated 5 May 2025 and filed on 6 May in Lacey v. State Farm (C.D. Cal.), a special master struck the claimant's supplemental briefs and denied the discovery relief she sought after her lawyers filed briefs built on unverified AI-generated legal research: about nine of 27 citations were wrong and at least two cited authorities did not exist. One lawyer's sworn declaration says the outline he circulated relied on generative AI features in CoCounsel, Westlaw Precision and Google Gemini, and that he could not tell whether particular errors came from his transcription or from a tool; co-counsel at the second firm say they used no AI tools and did not know AI had been used. The order makes the two firms jointly pay $31,100, states the client was not at fault and will not bear the awards, and imposes no penalty on individual lawyers.

An author and television producer, the subject of the Apple TV series 'Black Bird', sued Google, alleging that AI Overviews shown for searches about him in May and June 2025 falsely said he was serving a life sentence without parole, in one version for the murders of three women. He says he notified Google three times and received apologies attributing the statements to its AI, yet similar statements kept appearing. On 14 September 2026 the Northern District of Illinois denied Google's motion to dismiss as to two of the four challenged Overviews and dismissed the other two without prejudice. This was a ruling on the pleadings, not a finding that the allegations were proven.
